The Overlap Between Respiratory Bronchiolitis and Desquamative Interstitial Pneumonia: HRCT

When present, the distribution of the abnormalities such as adenopathy and emphysema was recorded. Surgical lung biopsy specimens were reviewed by a pathologist (T.V.C.) blinded to the findings on HRCT. Accumulation of pigmented macrophages in airspaces and around respiratory bronchioles Read More

The Overlap Between Respiratory Bronchiolitis and Desquamative Interstitial Pneumonia: Materials and Methods

The medical record of two index patients with PLCH associated with marked RB/DIP-like changes on biopsy were reviewed and summarized. To further characterize the relationship between RB/DIP and PLCH, we searched the Mayo Clinic database and identified 10 additional cases Read More

The Overlap Between Respiratory Bronchiolitis and Desquamative Interstitial Pneumonia

Pulmonary Langerhans cell histiocytosis (PLCH) is an uncommon interstitial lung disorder that occurs almost exclusively in smokers. Cigarette smoking has also been implicated in the development of respiratory bronchiolitis (RB)-associated interstitial lung disease (ILD) [RB-ILD] and desquamative interstitial pneumonia (DIP), Read More

Noninvasive Evaluation of Pulmonary Capillary Wedge Pressure by BP Response to the Valsalva Maneuver: Conclusion

Importantly, serial examinations in 11 patients showed that the measurement of the BP response to the VM also is useful for the assessment of changes in left heart filling pressure after a change of therapy. The identical slopes of the Read More

Noninvasive Evaluation of Pulmonary Capillary Wedge Pressure by BP Response to the Valsalva Maneuver: BP

With the release of the strain, the intrathoracic pressure decreases abruptly with a further sudden drop in arterial pressure (phase 3). Thereafter, as a result of an increased venous return, the arterial pressure overshoots to levels above control with a Read More

Noninvasive Evaluation of Pulmonary Capillary Wedge Pressure by BP Response to the Valsalva Maneuver: Discussion

In 11 patients (mean age, 51 ± 13 years), repeat measurements of the PCWP were performed 3.2 ± 4.5 months after the first examination. In these 11 patients, changes in the PAR predicted changes in the invasively measured PCWP with Read More

Noninvasive Evaluation of Pulmonary Capillary Wedge Pressure by BP Response to the Valsalva Maneuver: Statistical Analysis

Two measurements were performed within 3 to 5 min, and mean values for both PCWP and PAR were used for analysis. Immediately before each of the two VMs, the mean PCWP was invasively measured by a 7F balloon-tipped pulmonary catheter Read More

Noninvasive Evaluation of Pulmonary Capillary Wedge Pressure by BP Response to the Valsalva Maneuver: Materials and Methods

Patient Characteristics Forty-two patients (8 women) with a mean (± SD) age of 58 ± 13 years (range, 25 to 78 years) were included in the study, All were in stable clinical condition and had undergone elective cardiac catheterization as Read More

Noninvasive Evaluation of Pulmonary Capillary Wedge Pressure by BP Response to the Valsalva Maneuver

Pulmonary capillary wedge pressure (PCWP) is an important indicator of the hemodynamic severity of congestive heart failure (CHF) and is related to prognosis in these patients. In addition, PCWP is a useful tool for the guidance of therapy in patients Read More
